Head of the Department, Department of Radiology, Central Hospital, South Central Railway, Andhra Pradesh, India. Abstract: Osteoarthritis (OA) is a chronic, debilitating joint disease characterized by degenerative changes to the bones, cartilage, menisci, ligaments, and synovial tissue. Worldwide, osteoarthritis is the most common form of arthritis. Although the incidence of osteoarthritis increases with age, the condition is not a normal part of the aging process. The precise etiology of osteoarthritis is unknown, but biochemical and biomechanical factors are likely to be important in the etiology and pathogenesis. Biomechanical factors associated with osteoarthritis include obesity, muscle weakness and neurologic dysfunction. Sequelae from childhood diseases (eg: Developmental dysplasia, Perthes disease, Slipped capital femoral epiphysis, Juvenile rheumatoid arthritis), infection, trauma, osteonecrosis, inflammatory arthritis, idiopathic arthritic, femoral acetabular Impingement (FAI) etc may cause early onset of degenerative disease of the hip. The cardinal symptom of osteoarthritis is pain that worsens during activity and improves with rest. The pain is usually described as being in the groin or thigh for degenerative joint disease of the hip. Radiographs may be useful in confirming the diagnosis of osteoarthritis, assessing the severity of the disease, reassuring the patient and excluding other pathologic conditions. The radiographic hallmarks of primary osteoarthritis include nonuniform joint space loss, osteophyte formation, cyst formation and subchondral sclerosis; however, in early osteoarthritis, minimal nonuniform joint space narrowing may be the only radiographic finding. The main shortcomings of radiography are its insensitivity to change and its lack of soft-tissue depiction. AP views of the pelvis can be used to assess arthritic changes in the hips as well as the sacroiliac joints. Changes associated with the hip include superolateral joint space narrowing with subchondral sclerosis. The superolateral portion of the joint is the weight-bearing portion. Cystic changes can occur, and the femoral head can appear to be irregular. The osseous detail is better appreciated with CT scan. MRI can be helpful in evaluating cartilage loss and also in diagnosing additional associated pathologies like post-traumatic injuries, malignancy, neural foraminal impingement, infectious process. Ultrasonography has limited role and can be helpful in diagnosing cystic changes in the soft tissue about the joints but is not useful in the initial diagnosis of osteoarthritis. Conclusion: The diagnosis of degenerative disease of the hip (osteoarthritis) is based primarily on the history and physical examination while radiographic findings, including asymmetric joint space narrowing, subchondral sclerosis, osteophyte formation, subluxation and distribution patterns of osteoarthritic changes are helpful in confirming the diagnosis and assessing the progression of the disease. Radiography is primarily useful for the assessment of bony structures, US for ligaments and the synovium and MRI permits visualization of articular cartilage, intraarticular structures and pathologies. MR in knee osteoarthritis Bambang Budyatmoko MD, RS Premier Jatinegara Dept Of Radiology Faculty of Medicine University of Indonesia JL Diponegoro 71-Jakarta 10430 Indonesia. Abstract: Osteo arthritis or degenerative joint disease is the most common of the various articular disorder. Osteoarthritis is slowly evolving articular disease ,characterized by biochemical,histological and physical abnormalities of cartilage Osteoarthritis is common progressive disorder of movable joint characterized by deterioration and abrasion of articular cartilage and by new bone formation at joint surfaces and margin . Men and women are almost equally affected and clinically characterized by pain,limitation of motion and later deformity and slowly progressive disability mostly at the age more than 45 year. Pathogenesis of osteoarthritis is articular cartilage matrix metabolism . The function of articular cartilage include mechanical support and congruous joint motion. The capacity of the cartilage proteoglycan for holding water provide the hydration neccesarry to maintain elastic resistance to compression and help to generate lubricating abilities The earliest biochemical changes are increased water content,decreased proteoglycan and latter collagen disruption. With cartilage destruction,provide stimulus for blood vessel growth in the subchondral bone,which become eburnated and sclerotic. Leading to spur formation Osteoarthritis is disease of the joint that affects of all weight bearing component , bone,cartilage , meniscus,ligament Magnetic resonance Imaging (MRI) provide excellent soft tissue contrast and its capable of evaluating the soft tissue and bonny structures of the knee osteoarthritis in multiple image planes and sequences which significance advantages over other modality Image guided biopsy of spinal lesions Chou Hong Consultant Radiologist Department of Diagnostic Radiology Khoo Teck Puat Hospital, Singapore Abstract: Image guided biopsy of spinal lesions has become a routine method of obtaining tissue for diagnosis of neoplastic as well as infectious disease. It has proven to be accurate, safe and well tolerated in experienced hands with CT as the imaging modality of choice. Good knowledge of anatomy and precise needling technique is important to avoid potential complications. With the proper approach, awareness of surrounding vital structures and use of appropriate equipment, the procedure can be performed safely and with adequate yield. When properly performed, image guided biopsy of spinal lesions serve to guide clinicians in the management of spondylodiscitis as well as malignancies such as myeloma and metastatic disease. Ultrasound of glenoid labrum Ultrasound guided glenohumeral joint injection and hydrodistension Dr Harun Gupta MBBS,MD,DNB,MRCP(UK),FRCR(UK) Department of MSK Radiology Leeds Teaching Hospitals, Leeds General Infirmary, Leeds LS1 3EX, UK Abstract: Labral pathology is usually post traumatic and is an important cause of shoulder instability. Majority of lesions involve the anterior part of the labrum as within instabilities, anterior instability predominates. MRI with intra-articular contrast (MR Arthrography) is the modality of choice for evaluating patients with shoulder instability or internal joint derangement. Ultrasound can be used in such patients for assessing the integrity of the rotator cuff. However, there has also been an interest in evaluation of labrum with ultrasound due to its wide availability, lesser cost and in cases of contraindication to MRI. US features which confirm labral pathology include: paralabral cysts; lack of labrum in anatomical position; swollen labrum; displacement of labrum. The presentation will also cover other aspects of shoulder ultrasound such as assessment of subscapularis recesses; glenohumeral joint effusions and US guided injections into the glenohumeral joint. Characterizing Spinal Marrow Lesions using Diffusion Weighted MRI Dr Hirak Ray Choudhury. Department of Radiology & Imaging Advanced Medicare & Research Institute Hospital Kolkata Abstract: The MRI appearance of the bone marrow in routine evaluation using T1- weighted, T2weighted, and STIR sequences.is determined by the relative amount of protein, water, fat, and cells within the marrow. However the major determinants of signal characteristics in various pulse sequences depends on the fat and water content. Diffusion-weighted imaging (DWI) is based on the principle of mobility of water protons in tissue. The apparent diffusion coefficient (ADC) is quantitative motion of protons in tissues. The random, free motion of water protons in normal tissues results in relatively high ADC values (high signal on an ADC map). Densely packed cells within a tumor, or malignant infiltration restricts the motion of free water protons, thus decreasing the ADC (low signal on an ADC map). Diffusion weighted MRI is used in evaluation of vertebral collapse and infiltrating marrow lesions. A 1.5T MRI scanner was used in a study conducted in our hospital. After routine MRI sequences (T1, T2 , STIR and T1 with Gadolinium), all patients underwent DWMRI (SEEPI sequence) with b value of 400,800 and 1000, data taken in sagittal acquisition. Qualitative analysis was done in DW images with b value 1000 since these images show sufficient diffusion weighting and optimal contrast. Quantitative evaluation of vertebral body signal intensity was measured using apparent diffusion coefficient by placing a region of interest (ROI) cursor in the centre of each abnormal vertebral body and measuring the signal intensity in each pixel within the ROI. The qualitative (using variation in signal intensities) as well as quantitative (using ADC measurement) data was used to determine possible benign or malignant etiology of the marrow lesions. Statistical study and ROC curve showed a specificity of 83% and a sensitivity of 85.7% DWMRI with ADC values of vertebral lesions provide useful data to increase the radiological confidence in non-invasive diagnosis of vertebral marrow infiltrating lesions thus restricting the recurrent use of invasive procedures for diagnosis. Suprascapular neuropathy Dr. Joban Babhulkar DMRD, DNB Consultant at STAR imaging and research centre, Joshi Hospital Campus, Pune. Abstract: Suprascapular neuropathy is known cause of shoulder pain especially in the younger population. Often missed, it requires a high level of clinical awareness. It is usually caused by compression or traction of the nerve as its traverses the suprascapular or the spinoglenoid notch. Compression or traction of the nerve can occur due to space occupying lesions, traumatic injury or repetitive scapular movements. Asymptomatic isolated infraspinatus atrophy is very common in volleyball players. The signs and symptoms of suprascapular neuropathy can mimic those of a rotator cuff tear and often present a diagnostic dilemma. EMG and NCV have been classically employed to diagnose this neuropathy. We wish to establish the role of ultrasonography in the evaluation of suprascapular neuropathy. MRI of brachial plexopathies Dr Jyoti Panwar Sureka, MBBS, MD, FRCR Associate Professor at Department of Radiology, Christian Medical College, Vellore, India Abstract: Magnetic resonance imaging (MRI) has become the primary imaging modality in the evaluation of brachial plexus pathology, and plays an important role in the identification, localization, and characterization of the cause. Improvements in MRI technique have helped in detecting changes in the signal intensity of nerves, subtle enhancement, and in detecting perineural pathology, thereby refining the differential diagnosis. The brachial plexus abnormalities include trauma and a spectrum of nontraumatic causes, such as acute idiopathic/viral plexitis, radiation plexitis, metastases, immune-mediated plexitis, and mass lesions compressing the brachial plexus. MRI of impingement syndromes around ankle Dr Kulvinder Singh MBBS, MD Associate Professor & Head BPS Govt Med College for Women, Khanpur Kalan, Sonepat. Abstract: Ankle impingement syndromes are one of the most common cause of chronic ankle pain, restricted movements and instability, particularly in athletes and active people. Often, these conditions arise from chronic overuse, stress and microtrauma to the joint and the resulting altered biomechanics further aggravates the pathology. Clinically and anatomically, these syndromes have been classified as anterior, posterior, anteromedial, anterolateral and posteromedial. Magnetic resonance imaging (MRI) by virtue of excellent soft tissue resolution can demonstrate bony or soft tissue abnormalities in these syndromes. Imaging of Psoriatic Arthritis and Erosive Arthritis Kunihiko Fukuda Department of Radiology, The Jikei University School of Medicine. Abstract: Psoriatic arthritis (PsA) is an inflammatory arthritis associated with psoriasis. The radiological findings of PsA are characteristic. However, differential diagnosis between PsA of the interphalangeal (IP) joints and erosive osteoarthritis (EOA) is sometimes difficult. ●Radiological findings of PsA In the peripheral joints, distribution of the disease is asymmetrical. Swelling of the affected joints is present without juxta-articular osteoporosis. There are marginal bone erosions in the bare areas, and fluffy bone formation adjacent to the joints and the shaft of the bones. Involvement of more than two joints in the same digit can cause “sausage” digit. Progressive central osteolysis results in joint destruction. Joint ankyloses can occur in the phalangeal joints. New bone formation is also present in the entheseal sites, such as Achilles tendon and plantar fascia attachment. In the axial joint, the sacroiliac joints and the spine are involved. Bilateral sacroiliac joints can be involved, but asymmetrical involvement is more common. Asymmetrical non-marginal and/or syndesmophyte are present in the thoracic and lumber spine. DISH-like bulky paraspinal ossification is sometimes accompanies with syndesmophytes. Ankylosing spondylitis-like syndesmophytes with facet joints ankylosis can occur in the cervical spine more frequently than in the thoracolumbar spine. ●PsA and EOA: radiological findings of the fingers Both arthrides involve IP joints of the digits associated with inflammation. EOA involvement is limited to IP, 1st CMC, and triscaphe joints. Peri-articular inflammation is less pronounce in the EOA, therefore, sausage-like dactylitis is not present in the EOA. Radiographically, both EOA and PsA have marginal erosions and they may progress to central erosions. In typical case of EOA with central erosions, erosive patterns are sometimes called as “gull wing” appearance or “saw-tooth” appearance. In some cases with PsA, central erosion becomes wide spread osteolysis, which results in widening of the joint space. Combinations of pointing-shaped osteolysis of the proximal head and saucer-shaped osteolysis of the distal base appear “pencil-in-cap” type joint destruction. Bone formations are characteristic features of PsA. It occurs in the capsular, ligamentous, tendinous enthesis most of which are near the marginal erosions. Periostitis along the shaft is also present. These new bones appear fluffy in the early stage and become solid bones later. In case of EOA, bone formation is present as osteophyte at the cartilage-bone junction similar to conventional OA. Both arthrides eventually can produce bone ankylosis. MRI of Ankle Ligaments Dr.Kunwarpal Singh, M.B.B.S, DNB (RADIODIAGNOSIS) Asst. Prof. in department of Radio-diagnosis and Imaging Sri Guru Ram Das Institute of Medical Sciences & Research, Amritsar. Abstract: The ankle joint is the articulation between talar dome and lower ends of tibia & fibula. The plafond is the articulation between flat talar dome and flat surface of distal tibia.The complex anatomy of ankle provides diagnostic as well as clinical challenge to the radiologists and orthopedicians. Ankle injuries are the most common injuries sustained during sports and even day to day activities. Magnetic resonance imaging has opened new horizons in the diagnosis and treatment of many musculoskeletal diseases of the ankle. It demonstrates abnormalities in the bones and soft tissues before they become evident on other imaging modalities. The exquisite soft-tissue contrast resolution, noninvasive nature, and multiplanar capabilities of MR imaging make it especially valuable for the detection and assessment of a variety of soft-tissue disorders of the ligaments, tendons and other soft-tissue structures. Ultrasound of Tendon Lesions of the Ankle and Foot Dr Lisa LS Wong Hong Kong Imaging and Diagnostic Centre Hong Kong. Abstract: The superficial locations of the tendons in the ankle and foot make these suitable for assessment by high resolution ultrasound (HRUS). HRUS is readily available, economical and portable and provides non-ionizing multiplanar imaging of these tendons. It provides dynamic real-time assessment of these tendons and increases the diagnostic accuracy of the examination. It can diagnose most tendon disorders including tendinopathies, tears, dislocations, tenosynovitis and enthesopathies. These different tendon pathologies will be discussed in the lecture. HRUS provides real-time guidance for treatment of tendon pathologies. It allows precise needle replacement in the desired location, avoiding unnecessary trauma to any adjacent structures (e.g. neurovascular bundle) and increasing the efficacy of treatment. HRUS is time consuming and is best utilized to answer a specific clinical question related to a specific tendon rather than as a comprehensive examination of all tendons in the ankle or foot. When pathologies involving multiple tendons and/or extratendinous structures of the ankle and foot are suspected (e.g. in the setting of acute or severe trauma), MRI would be a more suitable imaging modality for more comprehensive assessment. Percutaneous management of Osteoid Osteoma Dr M V Chalapathi Rao Interventional Radiologist Dr Chalapathi Rao’s IR Centre Hyderabad. Abstract: Osteoid osteoma is an extremely painful benign bone tumor seen in young individuals. Osteoid osteoma is usually smaller than 2 cm in diameter. It has a male predominance and a male-to-female ratio of at least 2:1. The typical symptom is local pain that is described as severe, sharp, boring, typically worse at night. Pain is typically relieved with salicylates. The radiologic diagnosis is accurate when combinations of bone scintigraphy, radiography, computed tomography (CT), and magnetic resonance (MR) imaging are used. Together with clinical findings, a confident, imaging-based diagnosis is possible. The major differential diagnoses are Brodie’s abscess and occasional stress fractures. Total removal of the nidus of the osteoid osteoma, however, is usually the treatment of choice, and surgery has been considered the definitive treatment for many years. Difficulty in lesion localization, the consequences of extensive dissection, the need for prolonged recuperation, as well as the risk of incomplete removal and therefore recurrence of the lesion, make surgery a less desired option in the management of osteoid osteomas. Percutaneous resection of the nidus with CT guidance allows precise localization of the tumor with removal of less bone than at open surgery; hence, percutaneous resection has less risk than does open surgery. The trephine needle used at percutaneous resection, however, is often large, ranging from 7 to 10 mm in internal diameter. The large size of the instrument may incur risk of neurologic and vascular injury in some anatomic regions. Local complications such as hematoma, fracture or osteomyelitis are recorded. These disadvantages of percutaneous resection have encouraged the introduction of less invasive therapeutic methods, such as CT-guided core drill excision, radiofrequency ablation (RFA), alcohol injection, and interstitial laser ablation (ILA). At RFA and ILA, the insertion of an electrode or fiber through a well-placed needle allows direct delivery of energy from the machine to the tumor. Percutaneous RFA and ILA have proved to be safe, quick, and minimally invasive methods of management. Various studies have shown a high technical and clinical success rate, with minimal immediate and delayed complications and morbidity. Percutaneous RFA and ILA should be the methods of choice for treating percutaneously accessible osteoid osteomas. Imaging Of Talar Osteochondral Lesions Dr Mahesh Prakash, MD Additional Professor, Department of Radiodiagnosis, Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India Abstract : Osteochondral lesions of the talus (OLT) are common cause of ankle pain and disability, and they are often missed in the routine clinical evaluation of ankle injury. Imaging plays important role for evaluation of these lesions. The goal of imaging in these lesions is for their detection and demonstration of their position and extent. The assessment of cartilage and surrounding cancellous bone are very important. Plain radiography (Xray), computerized tomography (CT), bone scan and magnetic resonance imaging (MRI) are helpful in the detection and characterization of these lesions. Plain radiographs are useful in the initial evaluation of patients however low grade lesion can be missed. CT scanning can accurately identify and localize a lesion while defining its extent but accurate assessment of overlying cartilage is a limiting factor. MR imaging is best modality which can identify, localize, and define an osteochondral lesion with the advantage of assessing the integrity of the overlying cartilage. The present discussion will focus on the role of various imaging modalities with limitation and their advantages .Imaging features of osteochondral lesions on each modality will also be discussed. Posterolateral Corner Of Knee Dr Malini Lawande Consultant in MRI dept Dr Balabhai Nanavati hospital and Consultant in Innovision Imaging Abstract: It is called ‘dark side ‘of knee as it is difficult to evaluate it clinically and also it is often missed radiologically. It is an important structurally and functionally complex area. Unrecognized and untreated posterolateral corner injuries lead to residual instability and osteoarthritis as well as cruciate graft failure. US guided tendon therapy: needling of the tendon calcific deposit, needling of tendinopathy and injection in the tendon sheets Marina Obradov Sint Maartenskliniek Department of Radiology Hengstdal 3, 6522 JV Nijmegen The Netherlands Abstract: Extra-articular US guided musculo-skeletal interventional procedures are mainly focused on the tendons primarily in the case of the tendon calcific deposit, the tendinopathy and tenosynovitis. MRI and US of Biceps Tendon Abnormalities Mihra S. Taljanovic, MD, PhD, FACR Professor (tenured) of Radiology and Orthopaedic Surgery, The University of Arizona, Tucson, AZ. Learning Objectives: 1. Learn MRI and US imaging techniques in evaluation of the biceps brachii tendons and muscle 2. Learn normal anatomy and traumatic and pathologic conditions of the biceps brachii tendons and muscle on high resolution MRI and US The biceps brachii muscle is located in the anterior muscle compartment of the arm and spans shoulder and elbow joints. This muscle has two heads (long-LH and short-SH) and acts as supinator and flexor of the elbow and has role as dynamic stabilizer of the shoulder, particularly with the arm in abduction and internal rotation. Injuries of both proximal and distal biceps tendons can occur as a result of chronic stress/repetitive trauma or acute traumatic injury with the proximal biceps being more commonly affected. The LH of biceps tendon (LHBT) originates from the superior glenoid labrum and supraglenoid tubercle with known anatomic variants with respect to the labral attachment and less common congenital duplication or accessory slip. The SHBT originates from the tip of the coracoid process. Chronic repetitive microtrauma to the LHB tendon, (frequently in association with overhead throwing sports) leads to tendinosis and subsequent partial-thickness tear and eventual rupture. Tendinosis and tears of the LHBT are commonly associated with tears of the supraspinatus and subscapularis tendons, subluxation or dislocation from the bicipital groove, biceps pulley lesions, and various types of SLAP tears of the superior labrum. Acute ruptures of a healthy proximal LHB tendon are rare. Excess synovial fluid complex in the LHBT sheath, in the absence of a significant glenohumeral joint effusion is indicative of tenosynovitis. Diagnosis of the proximal LHBT lesions is best achieved with high strength MRI or MR arthrography. US examination provides excellent evaluation of the LBHT in the bicipital groove and most of time in the region of the rotator cuff interval. However, US evaluation of the biceps anchor and bicipitolabral complex is frequently suboptimal. Isolated ruptures of the proximal LHB tendon do not require operative treatment but tenodesis or tenotomy may be performed in symptomatic tendon ruptures or for severe tendinosis or partial-thickness tears. Tears of the biceps brachii muscle belly are rare and may be diagnosed equally well with MRI or US imaging. The distal BT is an extra-synovial structure without tendon sheath which is formed by contribution of the SH and LH of the biceps muscle approximately 7 cm above the elbow joint with attachment onto the radial tuberosity. These two tendons may have isolated attachments. The superficial fibres form a broad aponeurosis, lacertus fibrosus (LF) which sweeps across the antecubital fossa covering the superficial forearm flexors and protecting the median nerve and brachial artery. The bicipitoradial and interosseous bursae are located about the distal BT attachment site and may be distended (inflamed), frequently in association with tendinopathy and/or partialthickness BT tear. Distal BT injuries are usually result of acute trauma. If the BT is avulsed from the radial tuberosity and the LF is torn, the torn tendon retracts into the upper arm. With intact lacertus fibrosus, there is only minimal BT retraction, making the diagnosis more difficult. DBT tears frequently result in functional disability and surgical repair within 2 weeks is desirable. Distal BT retraction of less than 8 cm typically correlates with an intact LF, while larger retraction indicates LF tear. With the bifid DB, isolated rupture of a single tendon may occur. Retraction of the LHBT causes a deformity with a “Popeye sign,” mimicking a complete tear. Muscle retraction may not be present with isolated tears of the SH with intact LF. Traumatic and pathologic conditions of the distal BT can be diagnosed equally well with MRI or US. Avulsion Injuries Dr. Pramod Kolwadkar MBBS Ngp, MD Rad, AIIMS Delhi, DMRE Mumbai, FICRI Consultant Radiologist Abstract: Avulsion injuries can occur, either due to day to-day trauma, or during athletic and sporting activities. Whenever forcible pull of a strong ligamentous or tendinous attachment, pulls a fragment of bone, away from the rest of the bone - it is called avulsion fracfure,Commonest forces, producing awlsion fractures are-tension, stretching, torsion and shearing forces. Avulsion fractures, as well as sports injuries, are cofirmon in children & adolescent age, due to their relationship with growth. Thus most of the avulsion injuries are related to the growth spurt. Growth iissue is i,he weakest link in the bone. Hence avulsion fractures are common in children and adolescents. Avulsion fractures are commonest in apophyseal regiono physeal aren and articular epiplyseal region, in order of occurance. In this , talk, various examples of avulsion, fractures in apophyseal region e:g. Osgood- Schlatter lesion, are discussed. Similarly physea[and epiphyseal avulsion injuries have been demonstrated. Discussion also denotes, the various muscles involved, age - groups and the responsible sports or athletic activities. Epidemiological aspect is also dealt with. Approach To Pediatric Metabolic Bone Disease Dr. Rakhee Kumar Paruchuri MBBS, DNB, FRCR Assistant Professor, Nizam’s Institute of Medical Sciences, Hyderabad. Abstract: Metabolic bone diseases encompass a large spectrum of disorders that can result from genetic, endocrine, nutritional and biochemical disorders. Some of these conditions are reversible once the underlying defect has been identified and treated; some stabilize once the bones stop growing, while others require lifetime management. Metabolic bone diseases are commonly caused by abnormalities of minerals such as calcium, phosphorus, magnesium or vitamin D that affect bone as a tissue. These manifest as either of the two presentations, i.e, osteopenia or osteosclerosis. The radiographic changes may be diffuse or multifocal, although occasionally focal lesions may be seen. Some pathologies have characteristic appearances, such as rickets, scurvy and hyperparathyroidism, while some shownon specific features. Certain pathologies are seen only in neonates. Thus, a high index of suspicion is required with clinical and lab correlation to reach the correct diagnosis. MRI of tendons in the wrist DR. SANJAY DESAI MBBS, MD, DNB (RADIODIAGNOSIS) Fellow ISVIR, Erasmus Musculoskeletal Fellow (Europe). Consultant radiologist in Star Imaging centre, Pune. Abstract: Magnetic resonance imaging represents a relevant way to diagnostically assess the wrist with high-resolution, multiplanar imaging without employing ionizing radiation. It influences clinical and surgical diagnosis and management of wrist pathologies. The flexor and extensor tendons present typical low signal intensity and constant diameter on all sequences. Tendinopathy presents as signal and thickness changes on MRI, and may progress to partial- or full-thickness tears, with or without associated fluid and synovitis of the sheath (tenosynovitis). Tenosynovitis could be due to multiple causes besides overuse/degenerative changes (as in De Quervain’s tenosynovitis). An intersection syndrome refers to pain and swelling at areas of intersection between the tendon compartments – can be proximal (crossing between the 1st & 2nd extensor compartments at the distal dorsal radial aspect of the forearm) or distal (crossing between the 3rd and 2nd compartments at the level of tubercle of Lister). In cases of direct trauma to the tendon, it can be torn with / without retraction; in the latter the tendinous stumps need to be identified and the protocol tailored to the clinical question as required. In case of tendon injury at its bony attachments, the protocol needs to be altered and tendons followed upto their finger insertions for accurate identification of site (zone) of injury esp. in flexor tendons. Uncommonly, there can be a congenital absence / duplication of tendons which can be identified only if there is a high index of suspicion. Imaging of sesamoids and accessory ossicles of the foot Major General (Dr.) Sanjeewa Munasinghe RWP. RSP. USP. MBBS. MD. Consultant Radiologist, Army Hospital, Colombo, Sri Lanka. Abstract: Sesamoids are osseous structures, often small, found partially or totally embedded in a tendon or joint capsule, typically in locations where a tendon passes over a joint. The accessory ossicles are supernumerary bones that commonly derive from unfused primary or secondary ossification centres and are considered to be normal variants. There is wide variation in the prevalence and appearance of sesamoids and accessory ossicles in the foot. Though the clinical significance of presence of these osseous structures is probably minor, these bones may be associated with painful conditions due to various pathologies, including trauma, infection, inflammation, degeneration, arthritic and neoplasm. Therefore, knowledge of their presence and morphological variations is important to ovoid misinterpretation. Sesamoids and accessory ossicles share several imaging characteristics: They are usually small, well-corticated, ovoid or nodular, may be bipartite or multipartite, are found close to a bone or a joint. It may be difficult to distinguish between incidental variants and truly symptomatic bones. Although the recognition of pathological conditions in these small osseous structures are often challenging, imaging modalities including plain radiography, ultrasound, scintigraphy, computed tomography (CT) and magnetic resonance imaging (MRI) provide valuable diagnostic information. Plain radiographs confirm the presence of sesamoid or an ossified accessory bone and may suggest fractures of these. Cartilaginous or non-ossified accessory bones may be identified on ultrasound, which can also be useful in the evaluation of adjacent soft tissue for signs of inflammation and injury. Scintigraphy has the highest sensitivity in the localisation of the cause of foot pain to a sesamoid or an accessory ossicle but is non specific. CT readily demonstrates fracture and degenerative changes at a synchondrosis or articulation, and can also evaluate for increased sclerosis as seen in osteonecrosis. However, MRI is most useful in the evaluation of pathology associated with sesamoids and accessory ossicles. MRI findings are relatively specific for infection, osteoarthritis and fractures, and provides superior evaluation of adjacent soft tissues. Profile of wrestling injuries Dr. Shalini Agarwal (M.D, DNB, MNAMS, PGDHHM, Commonwealth Fellow) Professor, Department of Radiodiagnosis, Pandit Bhagwat Dayal Sharma, PGIMS Rohtak. Abstract: Wrestling is a popular sport in many countries around the world. Its origin can be traced back to the Sumerians as early as 5000 BC, and records of ancient Olympic wrestling date back to the Greeks in 708 B.C. In India its popularity is increasing everyday with wrestlers like Sushil Kumar, Yogeshwar Dutt and Amit Kumar Dahiya winning medals in Olympic & World Championships. The two styles of wrestling recognized internationally are Greecoroman, which made its debut in the first modern Olympics in Athens (1896), and Freestyle, included in the Olympic program in Saint Louis (1904). It is a contact sport with extreme physical demands and its practice is associated with an elevated incidence of orthopedic injuries. According to data from the centre for injury and policy, football and wrestling are the two sports with the high risk of serious injury to athletes. Reported match injury rates are as high as 30.7 injuries per 1000 athlete-exposures among college wrestlers second only to injury rates among college football players. In a study conducted by Myers et al (2010) it was found that the annual cumulative injury incidence was 6.49 injuries/1,000 wrestlers/year for the youth group and 29.57 injuries/1000 wrestlers/year in the scholastic group, this likely reflects the level of injury that present to the emergency department. Knee and shoulder the most frequently injured body parts and takedowns and sparring the most common activities at the time of injury. Increased duration of practice is associated with higher injury rate. Recurrent injuries especially ligament sprains and muscle strains are most common in wrestlers. Pasque et al (2000) reported that 6% of the athletes injured in the preseason suffered a re-aggravation of that injury during the regular season. The injury incidence rates have been found to be higher during tournaments than during practice. However, more number of injuries occur during practice as significantly more time is spent in practice sessions. There is wide variability in reporting these injuries, hence more studies need to be conducted. These studies help towards development of preventive programmes and hence are essential component of training of wrestlers. The speaker conducted a prospective study over 02 years involving 196 wrestlers and will be sharing her experience with the audience. HRUS: Approach In Arthritis Dr. Shamrendra Narayan MBBS, MD (Radiodiagnosis) Assistant Professor in Radiodiagnosis Sarojini Naidu Medical College, Agra Abstract: Diagnosis and classification of arthritis on part of the treating clinician is a challenge due to lack of specific clinical diagnostic criteria. The confusion is further added by many nonspecific and overlapping serology. X-rays have been the mainstay of the radiological assessment of joint disorders. However conventional radiography is not capable of assessing soft tissue as well as early bone abnormalities. Though the gold standard for the assessment of soft tissue abnormalities is MRI, in the last few years, musculoskeletal HRUS has made its presence felt among rheumatologist and radiologist. Ultrasound is an attractive imaging modality for evaluation of arthritis due to excellent resolution, lack of ionising radiation, non-invasiveness, portability and low cost. Dynamic and real-time assessment and Doppler imaging are additional benefits of this modality. MRI does score in evaluating the intra-articular derangements and marrow edema but that is hardly a consideration for evaluation of arthritis as tool for routine imaging. Axial skeleton is another area where HRUS has failed to mark its utility. Moreover the resolution of HRUS scores over MRI especially with freedom to compare contralateral and other involved joints in the same interaction. Extrapolating the clinico-pathological criteria into an imaging spectrum by HRUS is rewarding not only for making a diagnosis but also for follow up. Imaging Of Tuberculous Spondylodiscitis Sri Andreani Utomo Department of Radiology, Dr. Soetomo Hospital Faculty of Medicine, Airlangga University, Surabaya, Indonesia. Abstract: Tuberculosis (TB) remains endemic in most of the developing countries. TB not only in the lungs, but also in extrapulmonary sites, e.g. spine. Spinal TB is most often found in the lower thoracic and upper lumbar regions. Diagnosis is often difficult; clinical findings are usually non-specific and radiologic features may mimic those of other bacterial, fungal, inflammatory and neoplastic diseases. However, recognition and understanding of the radiological findings may help in diagnosis. The classic pattern of TB spondylodiscitis, characterized by destruction of two or more contiguous vertebral bodies and opposed end plates, disk infection, and commonly a paraspinal abscess and granulation. Rarely, TB spondylodiscitis may affect only a single vertebral body with or without disk involvement and this may lead to diagnostic confusion, metastatic disease and mycobacterial infection become more prominent in the differential diagnosis. Thus, awareness of the variability of imaging findings in spondylodiscitis is important in minimizing delays in diagnosis. Both malignant tumor and infection involve the bone marrow, revealed decreased signal intensity on T1-weighted images and increased signal intensity on T2weighted images. Malignant spinal tumor was differentiated from spondylitis by lack of disc involvement with tumor cells. The disc outline in spondylitis was usually irregular and disc intensity was increased on T2-weighted images. The suggested clue that can help differentiate between malignant spinal lesion and spinal infection are associated findings such as the endplate and disc involvements that mostly found in spinal infection. Plain radiography of tuberculous spondylodiscitis may demonstrate loss of vertebral height, disk space narrowing, erosions, indistinction of the end plates, paravertebral mass- es, and soft tissue calcifications. However, plain radiography is insensitive for the early detection of vertebral TB. CT is of great importance in demonstrating small, early foci of bone infection and the extension of the bone and soft tissue involvement. CT may also be used in the follow-up of patients under treatment with antituberculous chemotherapy. End plate destruction, fragmentation of the vertebrae, and paravertebral calcifications are adequately demonstrated. After administration of intravenous iodinated contrast paravertebral and/or epidural abscesses may show thick, nodular wall-enhance- ment and a sinus tract may ade- quately be delineated. Multiplanar capability and superior soft tissue contrast make MR imaging the modality of choice in the evaluation and follow-up of spondylodiscitis. A major advantage of MR imaging, compared with CT scan and plain radiography, is the higher sensitivity for detection of early inflammatory bone marrow changes and infiltrative end plate changes in the vertebra. MR imaging is mostly useful in delineating paravertebral, epidural, and intraosseous abscesses and in evaluation the extent of cord compression and the presence of intramedullary lesions. A positive culture or histopathologic analysis with CT-guided needle aspiration or biopsy specimens is required in the absence of pulmonary manifestations of tuberculosis and in diagnostic confusion, it is important for definitive diagnosis and adequate treatment. Imaging Of Primary Tumors Of Spine Dr. Sujata Patnaik Additional Professor Department of Radiology and Imageology Nizam’s Institute of Medical Sciences, Hyderabad. Abstract: Primary spinal tumours are rare and distinctive because of the diagnostic challenges. Early and appropriate institution of treatment results in better prognosis. Age at presentation, location of the tumour and pattern of the lesion are all important parameters for reaching a diagnosis. Among malignant spinal tumours metastatic disease, myeloma and lymphoma are the most common at diagnosis- metastatic tumours constituting 40-80%, followed by multiple myeloma and Plasmacytoma. Nonlymphoproliferative lesions accounts for only 2.5-8.5%. The spectrum of spinal tumours include bone forming tumours ( enostosis , osteoid osteoma , osteoblastoma and osteosarcoma), cartilage forming tumours ( Osteochondroma , Chondroblastoma and chondro-sarcoma), lymphoproliferative tumours ( multiple myeloma ,Plasmacytoma, lymphoma, leukaemia),tumours of notochordal origin (Chordoma), tumours of fibrous origin (benign and malignant fibrous histiocytoma and fibrous dysplasia), round cell tumour (Ewing’s sarcoma), primitive neuro ectodermal tumours (PNET) ,vascular tumours(hemangioma, epithelioid hemangioendothelioma , hemangiopericytoma) and others ( aneurysmal bone cyst (ABC), giant cell tumour (GCT). Rare tumours like leiomyoma, leiomyosarcoma, neurogenic tumour can occur in osseous spine. Conventional radiography is the initial diagnostic tool and also helps for decision regarding stabilisation of spine. CT and MRI are important for further evaluation, defining the extent (as spine is anatomically complex) and for staging of tumours. CT better evaluates vertebral body collapse and bone destruction; while MRI is preferred to assess epidural component and neural structure involvement. Newer advances like Dynamic contrast enhanced MR perfusion imaging, Proton spectroscopy and Diffusion imaging helpful in narrowing the differential diagnosis, differentiating responders from non-responders and residual lesions from recurrent lesions due to radiation necrosis. Radionuclide studies are sensitive to any area of increased osteoid reaction to destructive bone process to both lesions as small as 2 mm and as little as 5-15% of alteration in local bone turn over. PET/CT is useful for assessment of extent, staging, and follow-up of various spinal lesions. Angiography depicts vascularity and is used for selective embolization of hyper vascular tumours. Biopsy is required in most cases to establish final diagnosis. Osteiod osteoma and osteoblastoma occur in posterior elements and in younger age group. Nidus is characteristic and appears as lucency. When more than 1.5cm it is called osteoblastoma and smaller one is termed as osteoid osteoma. At times nidus may be obscured by sclerosis. Osteoblastoma may have aneurysmal cyst component with fluidfluid level. Four percent of all osteosarcomas occur in spine; commonly arise from posterior elements. Dorsal and lumbar regions are more commonly involved than sacrum or the cervical spine. Matrix mineralisation and lesions with varying amount of osteiod production, cartilage /fibrous tissue are frequently seen. Rarely tumour with marked mineralisation may produce ivory vertebra. Osteochondroma is a pedunculated cauliflower lesion with marrow or cortical continuity with parent vertebra. Spinous process is more common site than transverse process; which is more common than lesions in vertebral body. Chondroblastoma has predilection for growing skeleton. About 1.5 % of chondroblastomas occur in spine involving vertebral body and posterior elements. Spinal chondrosarcoma accounts for 4% of all chondrosarcoma. They frequently present in 3rd to 7th decade. Thoracic and lumbar vertebrae are more commonly involved than sacrum presenting as large calcified mass with bone destruction. Chondroid matrix mineralisation is better demonstrated on CT. Non-mineralised portion is highly bright in T2w images. Ring or arc like enhancement is characteristic. Multiple myeloma presents with punched out lesions and Plasmacytoma with collapse of vertebral body or expansile lesion having soap bubble appearance. These are common in elderly patients. Spinal lymphoma accounts for 1-3% of all lymphomas. Lesions may be lytic, sclerotic or mixed. Focus of bone marrow replacement and surrounding soft tissue mass without large areas of cortical destruction suggest lymphoma. Ewing’s Sarcoma and PNET occur in children mostly in 2nd decade. These lesions are seen in the posterior elements. Chordoma is most common primary spinal tumour occurring in 5th to 6th decade. Sacro-coccygeal (50%) and spheno-occipital region (35%) and vertebral body (15%) are the common locations. These present as expansile lytic lesions with soft tissue with areas of calcification. Hemangioma is the most common benign vertebral lesion having characteristic corduroy / honey-combing appearance and is often incidental finding. Hemangiopericytoma of spine is rare. ABC occurs in posterior arch and GCT in vertebral body. MR Imaging of Rotator Cuff Injury Dr Sunitha Linga Reddy Director – Lucid Medical Diagnostics Abstract: The supraspinatus,infraspinatus,teres minor and subscapularis muscles constitute the rotator cuff. The supraspinatus,infraspinatus,and teres minor tendons insert on the greater tuberosity whereas the subscapularis tendon inserts on the lesser tuberosity. The rotator cuff is a functional-anatomic unit rather than four unrelated tendons, and injury to one component may have an influence on other regions of the rotator cuff. Infection of the Skull bones, a less known entity Dr. Virinder Mohan Professor Emeritus, Radiodiagnosis, R M C H, Bareilly, U P INDIA Prof.Virinder Mohan and Dr.Nimisha Batra Postgraduate Deptt.of Radiodiagnosis and Imaging, Subharti Medical College, Swami Vivekanand Subharti University, Meerut INDIA. Abstract: Infections of bones is one of the common entity encountered by the Radiologists and the Orthopaedic Surgeons in their day to day practice more so in this part of the world. While long bones are the favourite site for pyogenic infection, vertebral column and the joints favour Tuberculous infection. Skull bones involvement in any form of infection is much less common and hence the correct diagnosis skull bones osteomyelitis remains a diagnostic challenge, more so since the imaging findings in skull bone infections may mimic many conditions in different age groups including primary benign and malignant tumours and the more common metastatic malignancy. However, a good clinical history and a good clinical examination and a high index of suspicion in a given case together with critical analysis of various imaging finding may clinch the diagnosis in majority of cases even before histopathology. Imaging of posterior tibial tendon dysfunction Dr. Adnaan Sheikh Associate professor of radiology University of Ottawa, Canada. Abstract : Posterior tibial tendon dysfunction is one of the most common problems of the foot and ankle. It occurs when the posterior tibial tendon becomes inflamed or torn. As a result, the tendon may not be able to provide stability and support for the arch of the foot, resulting in a flatfoot deformity. This talk will help you to understand the anatomical, biomechanical and imaging features of the posterior tibialis tendon dysfunction. Role of MRI in the post-operative shoulder Dr. Ankur Janakray Shah. Consultant radiologist and head Sadbhav Imaging Centre, a division of Gujarat Imaging Centre, Ahmedabad Abstract: Interpretation of MR Images of the post-operative shoulder can be a difficult task for the radiologist. There are numerous surgical procedures, all with particular approaches and complications. Surgical artifacts often make the study even harder to evaluate. Still, MRI can provide a great deal of information to the referring clinician regarding patients with recurrent or new symptoms after surgery. Most shoulder surgeries fall into one of two categories: 1) rotator cuff / impingement surgery and 2) labral / capsular surgery in patients with instability or pain from labral tear. It is very helpful to know the surgical history when deciding the study protocol and reviewing the MRI images. Gradient Echo images are more prone to metallic susceptibility artifacts from metallic and should be avoided. Fast spin echo sequences results in less artifacts compared to spin echo sequences and hence are more handy tool. MR arthrography plays a very important role in imaging of post-operative shoulder imaging. MRI findings have to be evaluated as per the procedure performed. As after every procedure, certain MR findings are related to the procedure and not considered as any pathology. At the same time it is very important to know the complications or abnormal findings that are likely to occur after a specific procedure to look specifically for them on MR images. It is important to remember that pathological findings in non-surgical patients may be “Normal” in post-operative situation. MRI Knee: Cruciate And Collateral Ligament Dr. Hemant Patel, DNB,MD,DMRE Professor at Gujarat Imaging Centre, postgraduate institute of Radiology, Ahmedabad, India Abstract: Injuries of the knee are common. Trauma and sports-related activities are the most frequent causes of knee injuries. Secondary to their role in maintaining stability, the ligaments of the knee are commonly involved in these injuries. To prevent long-term sequelae, early diagnosis and treatment, whether conservative or surgical— are key in planning management of these injuries. Because of its excellent oft-tissue contrast, magnetic resonance imaging (MRI) has proven very useful for identifying these important structures. The immediate post-injury period, clinical assessment of the knee is unreliable, which accentuates the importance of MRI as a diagnostic tool. Lumbar disc : Protrusion, Extrusion and Confusion Dr. Jinna Jagan Mohan Reddy Radiologist , Clinical Imaging Dept., MRI Section, Mafraq Hospital, Abu Dhabi, U.A.E. Abstract: Low back pain ( LBP) is defined as pain between the lower ribs and gluteal folds, with minimal radiation to the thigh and never below the knee. LBP with sciatica is defined when there is back pain together with radiating pain in the leg below the knee. Lumbar disc is common cause of low back pain. Lumbar disc can be classified in one of the following categories: Normal, Congenital/developmental variation, Degenerative/Traumatic, Infection/Inflammatory, Neoplastic and or Morphologic variant of uncertain significance. The data is categorized as possible , probable and definite. Congenital and developmental variations are congenitally abnormal eg. scoliosis or spondylolisthesis Degenerative/Traumatic : These include annular tears, herniation and degeneration. Trauma is not a major factor. Annular tears are fissures in annular fibres Degeneration may include desiccation, fibrosis, narrowing of disc space, diffuse bulging disc beyond annulus, defects and sclerosis of the end plate and osteophytes. Herniation is defined as a localized displacement of the disc material beyond the limits of intervertebral disc space (DEBIT). The disc material may be nucleus, cartilage, fragmented apophyseal bone, annular tissue. The disc can be focal (<25%), broad based (25-50%), and bulge (diffuse) . Herniated disc may be protrusion or extrusion. Protrusion, if the greatest distance in any plane between the edges of the disc material beyond the disc space is less than the distance between the edges of the bases (posterior margin of the disc) Extrusion , the disc material is greater than the distance between the edges of the base. Sequestration, displaced disc has lost continuity with parent disc. Migration is displacement of the disc from site of extrusion Inflammation/infection include infection and inflammation of the disc Neoplasia can be primary or metastasis Morphological variant of unknown significance suggest abnormal morphology of the disc In relation to posterior longitudinal ligament the disc material can be sub ligamentous, extra ligamentous, trans ligamentous or perforated. Volume of canal compromise of less than one third of the canal is mild, between one third and two thirds is moderate and over two thirds is severe. Composition of the displaced material may be characterized as nucleus, cartilaginous, bony, calcified, ossified collagenous, scarred, desiccated, gaseous or liquefied. Location: Anatomic zones and levels are defined using following land marks. Medial edge of the articular facets, medial, lateral upper and lower borders of the pedicles and coronal and sagittal planes at the center of the disc. On the axial plane these land marks determine the boundaries .Central zone, subarticular zone, foraminal zone and extra foraminal zone. In the axial plane moving from centre to right lateral is defined as central, right central, right subarticular, right foraminal or right extra foraminal. On the sagittal plane they determine the boundaries of the disc level, infrapedicular level, pedicular level and suprapedicular level. In the coronal plane anterior in relation to the disc means ventral to the mid coronal plane of the vertebral body. American Society of Spine Radiology and other societies have formed a task force to standardize different terminology used in lumbar disc as there is contradictory views and confusion about the terms used in routine practice. I will discuss the recommendations of the task force in the talk. Facet Joint Arthritis Dr. Lalitha Palle MBBS, MD, DNB, FICR. Associate Professor & Consultant Radiologist. MBA in Hospital Administration. Yashoda Hospitals. Hyderabad. Abstract: Arthritis of the lumbar facet joints can be a source of significant low back pain. Aligned on the back of the spinal column, the facet joints link each vertebra together. They are synovial joints and articular cartilage covers the surfaces where these joints meet. The common changes affecting the facet joints is degenerative disease. Inflammatory, septic and tubercular arthritis is relatively uncommon. Radiographs, CT and MRI can help pick up the disease and grade it. Imaging of patellar instability Dr Anupama Patil Director and Chief radiologist musculoskeletal imaging STAR diagnostic and research centre, Pune. Abstract: Patellar instability is a part of the patello-femoral pain/instability syndromes. The presence of patellar instability is essentially a clinical diagnosis , however radiology plays an important role in the assessment of a patient so that the orthopaedic surgeon may then plan his treatment protocol . It is extremely important that we know exactly what parameters are required by the surgeon and should be mentioned in our reports. The imaging modalities include plain radiographs, CT and MRI Scanning. Radiographs and CT help in the assessment of the Q angle which is an important determinant in the treatment protocol. The skyline view is another important x-ray yielding information which perhaps cant be gleaned on CT or MRI. The mainstay of imaging however is MRI, preferably with a high field strength so that the cartilage may also be adequately assessed. Various parameters such as patellar height, patellar tilt, presence or absence of trochlear dysplasia, integrity of the medial stabilisers of the knee and status of patella-femoral cartilage are assessed. This lecture aims to cover all of the above radiological parameters as well as some points on what the clinician/orthopaedic surgeon expects to be covered in our report. Imaging of the Lumbosacral plexus and its technical considerations Chhabra Avneesh Chief Musculoskeketal Radiology, Associate Professor Radiology and Orthopedic Surgery, UT Southwestern Medical Center, Dallas, Tx Abstract: The lumbosacral (LS) plexus is a network of nerves formed by the ventral rami of the L2 through S3 nerve roots. Its anatomy is complex, and its various branch nerves show a number of variations traveling obliquely in their retroperitoneal course and relatively straight in the lower limbs. Three-dimensional (3-D) imaging with multiplanar reconstruction is essential for evaluating neuromuscular anatomy in the abdomen and pelvis. This talk will focus on 3-D imaging of the LS plexus and its technical considerations, and the reader will gain knowledge of the 3-D anatomy and various pathologies of the LS plexus branch nerves. Cervical Disc Nucleoplasty Dr Ian Y Y Tsou Department of Radiology Mount Elizabeth Hospital, Singapore. Abstract: Intervertebral disc nucleoplasty or discoplasty is a method of disc material ablation. Unlike previous methods such as radiofrequency (RF) or intradiscal elecctrothermal annuloplasty (IDET), it does not cause such high temperatures during the procedure, as coblation rather than heat is used. Ablation of the intervertebral disc is aimed at causing vapourisation of the disc material, with resulting loss of volume and fibrosis, leading to retraction of the abnormal bulging or herniated portion of the disc. Although the manufacturer of the nucleoplasty product suggests using fluoroscopy as the method of imaging guidance, the radiologists at our centre (Mount Elizabeth Hospital, Singapore) realised that CT-fluoroscopy is a much safer option, in terms of reducing risk of vascular or nerve injuries, and also to be able to shorten the procedure time. The lecture will focus of the technique of the cervical nucleoplasty procedure utilising CT-fluoroscopic guidance, appropriate selection of patients for the procedure and potential complications and tips and tricks for safe performance of the procedure. Imaging of extradural lesions of the spine Jianling Cui, Jinjun Ren, Jiaojiao Fan, Yun Zhang Department of Radiology, The Third Hospital of Hebei Medical University, Shijiazhuang, Hebei 050051, China Abstract: The extradural lesions in the spine are not commonly seen. In this article we discuss the MRI features of pure extradural lesions of spine and their differential diagnosis. The nontraumatic spinal epidural hematomas (NSEH) are the most common lesions in the spinal epidural space, following by hemangioma, abscess, angiolipoma, metastasis, arachnoid cyst, meningioma. The hydatid cyst, multiple myeloma, lipomatosis, leukemia, lymphoma, hematopoiesis, ependymoma, hemagioblastoma, myelolipoma are rare. The MRI features of NSEHs are similar to intracerebral hemotoma, which are low signal or mixed signal in T2WI,some high signal areas in the T1WI, only the capsule is enhanced after Gd-DTPA injection intraveneously. The features of cavernous hemangioma are isointensity comparing to spinal cord on T1WI, very high signal on T2WI, obvious enhancement homogenously after Gd-DTPA injection. The low signal on T1WI and high signal on T2WI in a plain MR scan with irregular thick wall enhancement after contrast agent injection are the features of epidural abscess. Fat and blood vessel component exiting in one mass are the features of angiolipomas. A lot of epidural masses, such as neurilemoma, metastasis, meningioma, and multiple myeloma and so on, show isointensities comparing to spinal cord on T1WI and T2WI. Large cyst with CSF like signal inside are the features of epidural arachnoid cyst and hydatid cyst, former is relatively common.Conclusion: The pure epidural masses are clearly shown by MR imaging and making a diagnosis are not very difficult for the most cases High Resolution Ultrasound In Knee Joint Swellings Jyotsna Sen MBBS MD Professor, Pt B D Sharma PGIMS Rohtak, Haryana Abstract: Knee joint is one of the important weight bearing joints and is affected by a variety of disorders which can be congenital, traumatic, degenerative, metabolic or systemic (rheumatoid/psoriatic arthritis). High resolution sonography is emerging as a time efficient, non invasive, economical imaging tool for assessment of knee lesions because of its ability to visualize fibrillar microanatomy of tendons, ligaments, menisci and soft tissues. The knee joint is divided into four compartments- anterior, posterior, medial and lateral for anatomic localization and diagnosis of its pathology. The sonographic features of the various causes will be discussed. MRI and US of Biceps Tendon Abnormalities Kyung Jin Suh Professor Department of radiology Chief of Musculoskeletal Section Head of Diagnostic radiology, Nuclear medicine Dongguk University Gyeongju Hospital, College of Medicine, Dongguk University, Korea. and Radiation oncology Abstract : Objectives: • • • The pathologic changes of intraarticular LBT (long head of biceps tendon) cause shoulder pain and disability and also commonly related to rotator cuff pathology. Although the diagnosis of LBT abnormality on arthroscopy or even open surgery could be difficult, shoulder MR arthrogram may be a better modality providing a definite diagnosis. For the definite imaging diagnosis of various pathologic lesions of intraarticular LBT we introduce the illustrative cases of biceps tendon abnormality on shoulder MR arthrogram. Conclusion: • Arthroscopic Diagnosis of LHBT abnormality and instability is difficult • Neglected LHBT pathology – postoperative shoulder pain • • MR arthrographic findings of abnormal LBT are tendinopathy or localized hypertrophic change, instability and rupture of intraarticular long head of biceps tendon. Though biceps tendon abnormalities with rotator cuff disease or biceps pulley lesion are common association, arthroscopic surgical view is sometimes inappropriate to confirm the LBT abnormalities, especially in case of tendinopathy or localized hypertrophic change. MR arthrogram could be used as a most useful and reliable diagnostic modality for evaluating the LBT abnormalities. MRI of Rotator Interval Madhusudana Rao Tummala, M.D. Hurley Medical Center Department of Radiology One Hurley Plaza, Flint Michigan Abstract : Rotator interval is a triangular space on the anterior superior aspect of the shoulder. It is located at the level of the coracoid process between the anterior edge of the supraspinatus tendon and superior margin of the subscapularis tendon. The cartilage covering the humeral head serves as its floor. Rotator interval capsule is the anterior superior aspect of the gleno humeral joint capsule. Rotator interval capsule is reinforced externally by the coracohumeral ligament and internally by the superior glenohumeral ligament. The tendon of the long head of the biceps lies in the rotator interval extending from its origin at the supraglenoid tubercle towards bicipital groove. Biceps pulley stabilizes and maintains the biceps tendon in the bicipital groove. The complex anatomy and lesions of the rotator interval components, including the contents of the rotator interval, are important for the stability and proper functioning of the shoulder. The biceps instability, capsular and ligamentous abnormalities, adhesive capsulitis and lax shoulder will be presented. Ultrasound of the Elbow Dr Niraj Dubey, FRCR.

Role of CT in ankle and foot problems Nuttaya Pattamapaspong M.D. Department of Radiology, Faculty of Medicine, Chiang Mai University, Chiang Mai, Thailand. Abstract: The ankle and foot are complex structures comprising of multiple bones, joints, and soft tissue structures. Multiplanar and three-dimensional images which can demonstrate anatomical structures are required in most of the ankle and foot problems. Multidetector technology and post processing software have advanced computed tomography (CT) to produce high quality multiplanar reformatted and threedimensional images. Currently, CT is necessary in preoperative assessment of complex fractures of tibial pilon and calcaneus. CT helps demonstrate structural alteration from coalition, neuropathic arthropathy, and malunion fracture. This talk will emphasize on applications of CT in assessing complex fractures of the ankle and foot as well as review the utility of CT in other ankle and foot problems. Practical issues in scanning technique, image reconstruction, and interpretation will be discussed. Pitfalls in musculoskeletal magnetic resonance imaging Professor Wilfred CG Peh MBBS, MD, FRCP (Edin), FRCP (Glasg), FRCR Senior Consultant and Head, Department of Diagnostic Radiology, Khoo Teck Puat Hospital, and Clinical Professor, Yong Loo Lin School of Medicine, National University of Singapore Abstract: The practice of musculoskeletal radiology has become increasingly complex, with growing utilization of advanced imaging modalities. Magnetic resonance (MR) imaging is a powerful diagnostic imaging tool that is currently used in daily practice for the evaluation of a spectrum of musculoskeletal disorders. These applications include trauma to structures such as bones, joints, tendons, ligaments, muscles and nerves, as well as various diseases affecting these structures. While the latest MR imaging machines are able to show a larger number of musculoskeletal structures in more detail and with greater spatial resolution, a downside is the increased detection of clinically-unsuspected normal anatomic variants and generation of a variety of artifacts. Failure to recognize these anatomic variants and imaging artifacts may lead to diagnostic error and misinterpretation, and potential medicolegal problems. Inadequate imaging technique, lack of training/inexperience and failure to correlate with other imaging findings, particularly radiographs, are other potentially correctable pitfalls that may affect radiologists. MR imaging artifacts may not only affect image quality, but may also simulate pathological lesions. Artifacts may arise from patient motion or periodic motion, and from various protocol errors producing saturation, wrap around, truncation, shading, partial volume averaging and radiofrequency interference artifacts. Susceptibility artifact occurs at interfaces with different magnetic susceptibilities and assumes special importance with increasing use of metallic implants. Magic angle phenomenon is a special type of MR imaging artifact. In summary, recognition of various artifacts, variants and other potential pitfalls encountered in musculoskeletal imaging should help the practising radiologist achieve a more accurate diagnosis in daily clinical practice. Vertebroplasty: Current Status, Future Directions and Controversies Peter L Munk MDCM, FRCPC, FSIR Professor Radiology, Vancouver General Hospital Abstract: Vertebroplasty was first designed in the 1980s as a minimally invasive percutaneous treatment of vertebral hemagiomas and metastases. Subsequently vertebroplasty use was later expanded allowing for treatment of painful osteoporotic compression fractures. At present tens of thousands of these procedures are performed every year all over the world. A large body of literature exists reviewing the technical issues in performance of these procedures as well as documentation of their efficacy and complications. Over the years modifications of the original technique have been devised both for use in the spine as well as non spinal sites particularly the pelvis. This lecture will briefly review the technique for performance of vertebroplasty and also illustrate examples to cement injections outside the spinal axis (ie cemetoplasty). Some of the variants of vertebroplasty which have been developed will be briefly discussed as well as possible directions of future development. With the publication of two highly controversial papers in 2009 doubts about the efficacy of vertebroplasty emerged resulting in transient precipitous decline in the use of this technique, which has since been reversed. The issues surrounding this controversy will be reviewed. MR Evaluation of the Heel Pain Dr Raj Negi MD, DNB (Radiodiagnosis), FRCR (UK) INHS Asvini, Colaba, Mumbai Abstract : Heel pain or calcaneodynia is a common and frequently disabling clinical complaint which accounts for almost 15% of patients presenting to the primary health care facilities. A variety of causes both osseous and soft tissues are attributed to this complaint. MRI using its multiplanar capability, superior soft tissue contrast and lesion characterization has emerged as a mainstay in imaging of clinically ambiguous cases. Amongst the common known aetiologies the important ones are pertaining to the plantar fascia (fasciitis, rupture), Achilles tendon (tendinitis, Haglund’s deformity), calcaneum (trauma, infection, inflammation and tumor), bursae (inflammation), tarsal tunnel (entrapment neuropathy) and heel plantar fat (infection, painful heel fat pad). Each of these entities has specific imaging findings and in collaboration with the clinical inputs is well adjudged on MRI examination. The aim of this presentation is to outline the role of MRI in diagnosing the cause of heel pain and thereby guide the clinician as to the line of treatment. MRI of femoro-acetabular impingement: current concepts Remide Arkun,M.D. Izmir, TURKEY Femoroacetabular impingment (FAI) is a pathological entity which occurs when there is a conflict between the proximal femur and the acetabular rim and can lead to chronic symptoms of pain, reduce rate of motion in flexion, adduction and internal rotation of the hip joint. FAI is the major cause of early osteoarthritis(OA) of the hip, especially in young and active patients. Depending on clinical and radiographic findings, two types of impingement are distinguished. While, predominant morphological abnormality involves the femur in cam type FAI, predominant morphological abnormality involves the acetabulum in pincer type FAI. Cam and pincer lesions lead to distinct patterns of labral and chondral damage and long-standing impingement is likely a significant cause of previously described idiopathic hip joint degeneration. Cam type of impingement describes the femoral head and neck relationship as aspherical or not perfectly round. This loss of roundness contributes to abnormal contact between the femoral head and acetabulum. In case of cam FAI, the nonspherical shape of the femoral head at the femoral head-neck junction and reduced depth of the femoral waist leads to abutment of the femoral head-neck junction against the acetabular rim. Pincer type of impingement describes the situation where the acetabulum has too much coverage of the femoral head. This over-coverage typically exists along the front-top rim of the acetabulum and limits the range of motion and leads to a conflict between the acetabulum and the femur. This conflict results in the labral cartilage being “pinched” between the rim of the acetabulum and the anterior femoral head-neck junction. Most patients (86%) have a combination of both forms of impingement, which is called “mixed pincer and cam impingement,” with only a minority (14%) having the pure femoroacetabular impingement forms of either cam or pincer impingement. The role of imaging in FAI is to evaluate the hip for abnormalities associated with impingement and to exclude arthritis, avascular necrosis, or other joint problems on radiographs. Several imaging modalities such as conventional radiography, computed tomography(CT) and magnetic resonance imaging (MRI) have been used to identify the specific imaging findings of FAI. The diagnosis of FAI is based on the patient’s clinical history and physical examination and is further supported by findings at radiography, CT and MR imaging. It is important to identify the type of FAI and describe anatomical changes because surgical treatment differs for each type. Acetabular labrum, acetabular cartilage and femoral head cartilage are mainly affected in patients with FAI. Articular cartilage and labrum is assessed better with MRI in patients who have clinical and radiographic signs of FAI. It is important to know that surgical treatment of FAI is only suitable in patients without advanced degenerative changes and without extensive articular cartilage damage. The process of FAI is well demonstrated with MR imaging. The most important role of preoperative MR imaging in patients with FAI is to assess the exact extent of the damage already present within the joint. MR arthrography is superior to MR imaging in the detection and staging of acetabular labrum lesions. In MR imaging, high resolution and high quality images are necessary to make accurate assessment for labrum and cartilage lesions. Aside from standard axial, coronal and sagittal planes, an oblique plane paralleling the femoral neck is useful in assessing the anterior superior labrum. Alpha angle also can be measured from this plane. Using a cutoff of 55 degrees may result in a more specific diagnosis of an abnormal femoral head-neck offset. However, recent studies showed that alpha angle over 55 degrees also can be seen asymptomatic subjects. These examinations may show anterior and anterosuperior or anteroinferior acetabular labral damage. Cartilage lesions were most commonly found at the anterosuperior part of the acetabulum. The acetabular labrum, when damaged, shows increased signal on T2-weighted images that extends to the articular surface. This increased signal can either be well defined or ill defined as is seen in linear and degenerative tears, respectively. MR arthrography is considered the modality of choice for accurately determining the location and extent of labral avulsion and cartilage lesions. MR arthrography is considered the reference standard and clearly depicts the main diagnostic imaging features of FAI, cartilage, and labral lesions. The advantage of MR arthrography over nonarthrographic MR imaging is that the intraarticular contrast material distends the joint, separates intraarticular structures, and provides internal contrast to delineate the labrum and cartilage as distinct entities. Although the head-neck morphology could be measured without intraarticular contrast, the associated cartilage and labral abnormalities would be more difficult to see. Imaging findings currently described for FAI have not proved to be specific for diagnosing this disease process. Numerous studies have shown that a significant percentage of asymptomatic volunteers demonstrate multiple imaging findings of FAI. Correlation with symptoms and physical examination findings is paramount to diagnosing FAI. MR Imaging of the Menisci Dr Richa Arora MD , FRCR, MMED Assistant Professor Nizams Institute of Medical Sciences Hyderabad-500082 Abstract : Menisci are semilunar (C shaped) fibrocartilaginous structures composed of collagen fibres arranged circumferentially and radial fibres extending from the capsule between the circumferential fibres. They are important both structurally and functionally and are involved in distribution of stresses over the articular cartilage, absorption of shocks during axial loading, stabilization of knee in both flexion and extension, minor contribution towards secondary stabilization after cruciate ligament injuries and joint lubrication. MR imaging plays an important role in diagnosing meniscal pathologies and MR of the knee is the most frequently requested MR among all joints. MRI Features Of Seronegetive Spondyloarthropathy Dr. Sandeep Velicheti Assistant professor, Pinnamaneni Siddhartha Medical College. Consultant radiologist & Diagnostic Neuro radiologist Sentini hospital, Abstract: Early features of ankylosing spondylitis and other seronegetive arthropathy can be very well demonstrated in MRI. Bilaterality and characteristic pattern of involvement at synovial portion of S.I joint helps to differentiate from infection. Chronic changes are evident by sclerotic signals which are seen well with CT scan and plain radiographs. MRI is currently included in the diagnostic criteria of spondyloarthritis proposed by the ‘Assessment of Spondyloarthritis International Society’ Disco-vertebral junction which is also involved in the inflammatory process is well detected in MRI. Apart from these, changes in the facet joints, enthesopathy or enthesitis can be well depicted on MRI; these changes are very difficult to pick up in plain radiographs. MRI changes precede years before it is seen in plain radiographs Hybrid Imaging Applications in Musculoskeletal Disorders Seoung-Oh Yang, M.D. Departments of Nuclear medicine, Asia Cancer Center (DIRAMS), Busan, Korea (South). Abstract: Hybrid imaging (SPECT/CT, PET/CT, PET/MR) were introduced recently. PET/CT offers a hardware solution for viewing functional anatomic images simultaneously. FDG-PET imaging has been most commonly used to evaluate primary bone and soft tissue tumors, metastases, myeloma. Due to low incidence of primary musculoskeletal tumors only limited data are available to estimate the clinical usefulness of PET. FDGPET also been evaluated for monitoring treatment effects in patients with sarcomas. Limitations of FDG-PET/CT are the differentiation of low grade malignancy from benign tumors and relatively low sensitivity in detecting osteosclerotic metastasis. The accuracy may be increased by using more specific tracer such as 18F-fluoride, 18FFMT(tyrosine) and 18F-FLT(thymidine). PET/CT obviously provides advantages in the evaluation of musculoskeletal tumors with excellent capability of anatomic localization and capability of whole body imaging. SPECT/CT with the integration of CT and SPECT gantries has enhanced bone scan by providing accurate lesion localization and characterization of equivocal and solitary bone lesions. SPECT/CT has been proven to increase sensitivity and specificity of bone scan. SPECT/CT should be applied whenever equivocal findings of planar bone imaging occur. The key impact has been enhanced diagnostic confidence in the differentiation of benign from malignant skeletal lesions made possible by accurate localization of lesions to facet joints, vertebral bodies, or pedicles due to the exact coregistration of CT and SPECT as well as consideration of sclerosis or lysis within the lesion seen on CT. Several studies comparing planar, SPECT, and SPECT/CT in equivocal lesions have demonstrated a substantial improvement in specificity with SPECT/CT. Whole-body PET/MRI imaging demonstrated a good image quality with near perfect correlation of findings in comparison to PET/CT. Both local extent within the bone and invasion into the adjacent muscles can be determined more accurately on PET/MRI than on PET/CT. Although FDG PET/CT has been shown to be more accurate when assessing the lung for metastases, MRI has been reported to have higher accuracy than FDG-PET/CT when assessing the liver and the bone for distant metastases. Diffuse metastatic bone marrow infiltration may be difficult to detect on PET imaging and is typically overlooked on CT, but they can be detected reliably with MRI. Therefore, PET/MRI will possibly prove of higher diagnostic accuracy than CT and PET/CT, and can be expected to provide a more accurate TNM-stage. On the other hands, FDG PET/MRI protocols will have to be designed individually for each tumor entity. DWI, especially in precise co-registration with PET, offers increased the sensitivity of metastases detection and promising opportunities for tumor therapy effect monitoring. Therefore, adding DWI to an anatomically-oriented PET/MRI whole-body protocol seems to be indispensable for staging purposes. MRI appearances of the wrist and carpal ligaments: a pictorial review Dr Srikanth Narayanaswamy Consultant Musculoskeletal Radiologist Sakra World Hospital . Abstract : Chronic wrist pain can be related to carpal instability which is based on the integrity of the wrist and carpal ligaments. Injury to these ligaments can be a source of pain with or without associated instability. Adequate knowledge of anatomy of these structures provides the foundation in making the accurate radiological diagnosis. Advancement of technology has revolutionized the understanding of these complex structures. MRI remains the modality of choice in investigating the wrist and carpal ligaments. In this exhibit, we will provide a descriptive illustration of the MRI anatomy of the main wrist and carpal ligaments.

Subscapular injuries related to acromiohumeral instability of shoulder impingement syndrome Tae Yong Moon Pusan National University Yangsan Hospital, Yangsan, S. Korea Objectives: To evaluate the relation of subscapularis injuries with acromiohumeral instability of shoulder impingement syndrome Imaging of Pediatric Knee injuries Suphaneewan Jaovisidha, MD Professor of Radiology Ramathibodi Hospital, Mahidol University, Bangkok, Thailand. Abstract: The knee is the joint that frequently injured because it is intrinsically unstable. The curve surfaces of femoral condyles articulate with the flat proximal tibia. And because of this anatomy, ligaments & menisci play a crucial role in knee stabilization Children are susceptible to injuries because of numbers of developmental factors. The first factor is lack of developed complex motor skills. The second is the open physes are more vulnerable to stress than tendon, and they needs 4-5 times of force to tear the tendon compare to avulse the physis. The third factor is musculoskeletal imbalance. The limb length increases 1.4 times from age 6-14 but the limb mass increases by more than 3 times. The larger increase in mass forces the muscle to generate greater force to move the limb, creating strain to the tendons, myotendinous junction (MTJ), and the physis. Extra-articular soft tissue injuries comprise 82.7% of clinical diagnosis of knee injury in children. The other diagnoses are patellar disorders (8.8%), intra-articular soft tissue injuries (4.3%), overload/overuse injuries (3.2%), and fractures (1.1%). Trauma in children often involves radiolucent structures & difficult to access on plain radiographs, and magnetic resonance (MR) imaging has become an important modality because it can show the physis, cartilage, meniscus & ligaments Many diagnostic MR criteria in children are similar to those used in adult patients. The content will emphasize on the differences. For example, kissing contusion, which is marrow edema associated with anterior cruciate ligament (ACL) tear in adult, was reported in children without ACL tear due to more laxity of ACL in this age group. In children, chondral/osteochondral injury is more frequent than ACL and meniscus injury. It was considered significant because it may predispose premature osteoarthritis, and it may cause joint locking and pain due to the loose body. Complications of physeal injuries consisted of growth arrest which directly proportionate to increasing Salter-Harris number, angular deformity, leg length discrepancy, bone bridging and then long term disability Imaging of hip joint in children Dr N.L.N.MOORTHY Prof of radiology Gandhi medical college/ hospital Secunderabad INDIA Abstract: Diseases of hip joints are common in paediatric age group . They include developmental dysplasia of hip,perthes disease, septic arthritis, tuberculosis hip joint, slipped capital femoral epiphysis, bone cyst, fibrous dysplasia, juvenile rheumatoid arthritis etc. They usually present with limp,painful hip, irritability of joint .Imaging plays a major role in making appropriate diagnosis. The radiological investigations include plain radiography, (antero posterior and frog leg views), ultrasound, MRI and CT scan . The various lesions that affect the hip joints in children are broadly classified into Congenital : developmental dysplasia of hip, congenital short femur, proximal focal femoral deficiency Developmental : Leg Calve Perthes disease, coxa valga, coxa vara Inflammations: juvenile rheumatoid arthritis, dermatomyositis Trauma: slipped capital femoral epiphysis, apophyseal injuries Infections: transient synovitis, tuberculous arthritis, septic arthritis Benign neoplasms : unicameral bone cyst, aneurysmal bone cyst, esoniphilic granuloma Malignant neoplasm: lymphoma, leukemia, ewing’s sarcoma Developmental dysplasia of the hip: Ultrasound is highly specific in the diagnosis and shows a rounded acetabular roof and an alpha angle of less than 50%. Proximal femoral focal deficiency: Plain radiographs show the osseous defects Legg-Calve-Perthes disease: Though radiography is sensitive MRI is used in early detection where the lesion appear as low T1 and High T2 signal intensity and with no enhancement on contrast administration. Transient synovitis : On imaging there may be joint space widening with hip effusion. Juvenile rheumatoid arthritis: Ultrasound detects the presence of joint effusion. MRI with contrast is very sensitive for assessing the soft tissue edema, proliferative synovium. Slipped capital femoral epiphysis: Plain radiography shows widening , lucency and irregularity of the physis on the affected side. The various imaging features of other conditions will be discussed. Sclerosing Skeletal Dysplasias Prof. Kakarla Subbarao Emeritus Professor Nizam’s Institute of Medical Sciences, HYDERABAD. Abstract: Sclerosing bone dysplasias constitute a variety of abnormalities with a wide range of clinical, genetic and imaging features. Conventional radiology plays a major role. Several genes have been described and when disrupted cause, different types of bone dysplasias. These include osteopetrosis, pycnodysostosis, osteopoikilosis, osteopathia striata, Engelman dysplasia, dysosteosclerosis and Van Buchem. Melorrheostosis and Ribbing disorders or non-heriditory. Knowledge of the radiological features is essential for the diagnosis as histology does not help much. Acquired sclerosing skeletal disorders are not included in this presentation. Prof Kakarla Subbarao MRI of the labroligamentous complex Quek ST Head and Senior Consultant, Department of Diagnostic Imaging, National University Hospital Clinical Director, Breast Screen Singapore Programme, National University Health System Abstract: Shoulder injuries are increasingly encountered as a result of sporting activities due to lifestyle changes. The assessment of patients with shoulder injuries include assessment for instability which may result from injury to the dynamic or static stabilisers of the shoulder joint. This talk reviews the anatomy of the gleno-labroligamentous complex (a key component of the static stabilisers of the shoulder joint), the more common forms of injuries involving the complex as well as some pitfalls in diagnosis. Diagnosis of subtle bone erosions in digital environment Shigeru Ehara, M.D. Morioka, Japan 1. Changes in treatment Early application of DMARDs and new biological therapy, including anti TNF agents, have significantly improved treatment outcome of rheumatoid arthritis. Objective of the imaging diagnosis has shifted to early detection of subtle arthritic changes. In addition, imaging diagnosis of early RA changes is currently performed in the digital environment with limited spatial resolution. Among imaging studies, plain radiography, including storage phosphor and flat panel detector (FPD) radiography, is aimed to detect subtle bone erosion. Ultrasound is suited to detect superficial lesions, particularly synovitis of surface small joints, and MR imaging is used to detect synovitis and bone marrow changes in almost any locations. 2. Characteristics of current digital imaging system Limited spatial resolution and high contrast resolution are characteristic in the current digital system, compared with the conventional film-screen radiography. Thin cortex is close to the limitation of spatial resolution of the digital system. Fine detail radiography using fine-grain industrial film (e.g. Kodak M) used to be applied (Radiology 112:37), but now it is not readily available. In currently used storage phospher radiography, resolution is limited, < 2.5 lp/mm, compared to 3-8 lp/mm for conventional system. On the other hand, exposure latitude is as high as 10,000:1 (30-40:1 in screen-film system). FPD radiography is characterized by increased detective quantum efficiency, exposure reduction of 50-75%, and improved contrast detectability (Radiology 231:506). Digital tomosynthesis is currently used sectional imaging system with relatively low radiation exposure with high spatial resolution, and it is suited to detect early arthritic changes (Aoki). 3. Radiographic diagnosis of early or subtle RA Early RA is defined as RA of less than 3 months after onset. Early or subtle signs include surface erosion, soft tissue swelling, and subchondral bone resorption. Erosion is highly specific for RA, and its types include marginal, subchondral, and pressure. Surface erosion, another type, is partial wasting of subchondral lamina, which is close to the limitation of resolution, 0.05-0.1 mm. Limitation of the resolution of current system is similar, at 0.2-0.05 mm. Norgaard erosion is a small notch with sclerotic border in asymptomatic population, and used to be considered a normal variation. However, such small superficial erosion of proximal phalanx may be considered to be an early sign of early RA (Br J Rad 53:63). Soft tissue swelling, another early change, depends on contrast resolution, and it represents either joint effusion or synovial inflammation. Subchondral bone resorption may be an early sign, but it is more commonly seen in later stages. 4. Early detection of marrow lesion on MRI Early imaging features of RA may lack radiographic findings. Bone marrow change, only assessed on MR imaging, may be seen two years earlier (Østergaard). Detection and distribution of early RA changes are assessed by MR imaging. Whole body and whole hands MR images are used to detect bone marrow edema on T1W & T2W images and synovitis on T2W and Gd-contrast images. 5. Conclusion Overall performance of the digital system for early arthritis is comparable to, but not better than, the conventional system. Continuous quality control of imaging system is important to detect early and subtle arthritic changes in a reproducible manner. Athletic Pubalgia, “Sports Hernia” and Anterior Pelvic Pain Dr THAM Seng Choe Consultant Radiologist Mount Elizabeth Novena Hospital Singapore Abstract: Athletic pubalgia, also known as “sports hernia”, is not an uncommon cause of anterior pelvic pain in athletes. It is associated with sports that require hip flexion with trunk rotations such as soccer or hockey. The adductor longus and rectus abdominis muscles attach at the pubic bone. An imbalance in these antagonistic muscles is postulated to contribute to athletic pubalgia. The adductor longus - rectus abdominis aponeurosis is frequently injured as a result. MRI is typically the study of choice for athletic pubalgia. Due to the unique anatomy of the involved structures, proper understanding of the anatomy and dedicated imaging of this region is required. Careful and proper evaluation should be made as other causes, such as hip pathologies, may not only mimic athletic pubalgia but also occur in concurrence with it. Accurate diagnosis is important for successful treatment and faster return to play for the athlete. The comparison of tomosynthesis, computed tomography and X-rays in the imaging of peri-prosthesis after THA Ma yimin, Su yongbin, Shao Hongyi et al, Department of radiology, Jishuitan hospital, Beijing, 100035 China Abstract: Objective - To compare the definition of structures around the prosthesis among tomosynthesis (TOMOS), computed tomography(CT), and digital radiography(DR). Material and Methods Twenty consecutive patients (mean age, 61.0±10.4 years; range, 36–82 years) with THA referred for TOMOS, CT and DR hip imaging. Three senior attending radiologists independently evaluated the definition of acetabulum region, prosthesis, and proximal femur region, in TOMOS, CT and DR images. Scores calculated would be analysed via Generalized Estimating Equations. Results TOMOS’s image quality of the acetabulum and proximal femur region was rated significantly superior to CT’s(P <0.001). DR’s image definition was significantly better than CT’s(P =0 - 0.0077). Conclusion: Compared to CT, TOMOS and DR imaging techs can reduce artefacts caused by prothesis, which made the image definition better. Ultrasound evaluation of lower limb nerves Dr.Srinadh Boppana Consultant radiologist Kamineni hospitals, L.B.nagar, Hyderabad Abstract: Peripheral neuropathies are relatively common clinical disorders. They can be divided into compressive (entrapment) and non-compressive neuropathies based on their etiology. Entrapment or compressive neuropathies are important and widespread debilitating clinical problems, especially in patients with predisposing occupations or with certain medical disorders. Although nerves may be injured anywhere along their course, peripheral nerve compression is often caused by mechanical dynamic compression of a short segment of a single nerve at a specific site most frequently as it passes through a fibro-osseous tunnel, or an opening in fibrous or muscular tissue. High-resolution Ultrasound is a simple, cost effective diagnostic tool that allows direct imaging of the involved nerves, identification of the underlying cause and severity of the compression. A spectrum of extrinsic causes of entrapment, such as tenosynovitis, ganglia, soft-tissue tumors, bone and joint abnormalities, and anomalous muscles, can also be diagnosed with ultrasound.
